通过浸轧含有维生素E醋酸酯的硅酸乙酯溶胶,经预烘和焙烘等工艺,使维生素E醋酸酯固着在棉织物上,从而赋予棉织物维生素E保健功能.研究了溶胶制备工艺(硅酸乙酯用量、盐酸用量、搅拌时间)、预烘时间等对整理效果的影响,确定了较佳整理工艺:m(织物):m(硅酸乙酯)=20:20,盐酸6.0mL,预烘120min,使用定性显色和定量滴定方法测定了织物上维生素E醋酸酯含量.讨论了维生素E在棉织物上的而寸洗性以及皂洗次数对织物白度、强力和手感的影响.
In order to endow cotton fabric with health care function, Vitamin E acetate was fixed on cotton fabric by padding the ethyl silicate sol containing vitamin E acetate using predrying and curing technics. The in- fluences of preparation of sol including the dosage of ethyl silicate and hydrochloric acid and agitate time and the predrying time on the effect of finishes. The optimum finishing technics was obtained: m(fabric):m(ethyl silicate)= 2.0:2.0, 6.0 mL of hydrochloric acid, predrying time was 120 min. The vitamin E content on the fabric was measured by qualitative developing and quantitative titration methods. The washfastness of vitamin E on cotton fabric and the effects of soaping frequency on the whiteness, strength and handle of fabric.
